Preimplantation Genetic Screening

Preimplantation Genetic Screening (PGS) is a test done on fertilized embryos before implantation. This procedure makes it possible to choose only the embryos with the right number of chromosomes from all of the embryos made by a patient in a given period of assisted reproduction.

Using array Comparative Genomic Hybridization (aCGH), we can look at all 24 types of chromosomes. This way, we can rule out fetal aneuploidy before implantation.

When is PGS done?

Advanced Maternal Age

Implantation Failure

Male Factor

Frequently Asked Questions

Preimplantation genetic screening for structural chromosome rearrangements is used to find possible chromosomal abnormalities in the developing embryos. Chromosomal disorders are caused by changes in the order of chromosomes, such as translocations, inversions, and deletions.

PGT can make sure that the embryo chosen for transfer has the right number of chromosomes. This makes it less likely that the IVF cycle will fail and less likely that the pregnancy will end early.
